Title: Improvements in and relating to control units for air suspension levelling valves
Inventor: NEAL BRIAN PATRICK
IPC: B60G17/052
Filed: 1960-12-02
Abstract: 956,870. Adjusting vehicle height. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. Nov. 21, 1961 [Dec. 2, 1960; Feb. 21, 1961], Nos. 41482/60 and 6340/61. Heading B7D. In a pneumatic motor vehicle a control unit connected between a levelling valve and an air spring comprises a control valve actuated by a pressure responsive member to restrict or prevent communication between the levelling valve and the spring during high frequency oscillation of the suspension as occurs when crossing rough or uneven terrain. In Fig. 1, a levelling valve of the type described in Specification 895,433, wherein a lever 12 actuates a plunger 13 co-operating with a disc valve 15, is provided with a piston 20 connected to the lever 12 and working in a pumping chamber 25 communicating through a check-valve 27 with a chamber 29 below a diaphragm 31 connected to a control valve 36. During rapid displacement of the lever 12 the piston 20 supplies air to the chamber 29 to lift the diaphragm 31 and the valve 29 thereby closing passages 34, 35 which connect a passage 40 from the levelling valve with a port leading to the air springs, so that air may only pass to the springs through a restricted compensating passage 38. A choke 30 vents the chamber 29 slowly to prevent closing of the valve 36 during slow displacement of the lever 12. In Fig. 2 a control unit for connection between a levelling valve and an air spring comprises a diaphragm 61 with a central bush 64 connected to a valve plunger 77 formed with a circumferential groove 78 normally aligned with a passage 72 to provide communication between a port 74 leading to the levelling valve and a port 76 leading to the air spring. A chamber 62 on one side of the diaphragm is subject to the air spring pressure whereby rapid pressure changes at the spring displace the groove 78 from alignment with the passage 72. A choke 67 equalizes the pressure across the diaphragm 61 during slow changes in air spring pressure.

Title: Improvements in or relating to power controllers for hydraulic power transmission systems
IPC: F15B11/17
Filed: 1965-09-30
Abstract: 1,128,657. Controlling hydraulic transmissions. LINDE A.G. 30 Sept., 1965 [30 Sept., 1964], No. 41650/65. Heading F2D. [Also in Division F1] Two or more adjustable output pumps 1, 4 in respective circuits of an hydraulic transmission system, e.g. in an excavator, are controlled simultaneously by a spring-loaded stepped piston 7, or a plurality of pistons, having faces 10, 11 respectively subjected to the output pressures of the pumps 1, 4, i.e. the pressures in the pressure lines of the circuits, so that the sum of the output pressures controls the adjustment of the pumps. The piston step areas, or individual piston areas, correspond to the power consumption of the associated pumps, to prevent the maximum output of the power source, e.g. an I.C. engine, from being exceeded. The loading spring and leverage characteristics may also be related to the piston surface areas.

Abstract: 1287586 Cathode-ray tube circuits TWATSU ELECTRIC CO Ltd 22 Aug 1969 [23 Aug 1968] 41934/69 Heading H4T In a sampling oscilloscope, the frequency of the sampling pulses is automatically synchronized, e.g. to a sub-multiple of the input frequency, by use of the differentiated output of the sampler to control the frequency of sampling pulses in such a way that the differentiated output tends to zero. The automatic synchronizing system includes means for inhibiting its control during the flyback interval of the low speed sawtooth sweep supplied to the oscilloscope. Figs. 1 ... 3 (not shown), relate to block diagrams of a known synchronizing arrangement including a differentiating circuit after the sampler. In Fig. 4, the output of the sampler at 43 is supplied to the Y plates of the oscilloscope under control of pulses from a circuit 45 synchronized with an input 44. Each pulse from circuit 45 initiates a high speed sawtooth wave from generator 46 which is compared at 47 with a low speed sawtooth (or staircase) wave from generator 49. Each sampling pulse generated at 48 at the time of coincidence of outputs from generators 46 and 49 is fed to the sampler 42 so as to operate at successively different instants in successive cycles of the monitored input at 41. As shown in Fig. 6, a gate is inserted before or after the differentiating circuit 141 so as to inhibit operation of the automatic synchronizing system during the flyback of the wave from generator 49.

Title: Method and apparatus for recovering phase components from a  mixture of solids and liquid
IPC: B01D21/00
Filed: 1973-09-12
Abstract: 1445140 Settling crystallised solids; centrifugal separators; crystal separation USS ENGS & CONSULTANTS Inc 12 Sept 1973 [12 Sept 1972] 42921/73 Headings B1D, BIG and B2P [Also in Division C1] A solids-liquids mixture, e.g. crystals and another liquor, is separated by passing the mixture to a separating zone, which may comprise a settling tank, a centrifuge or a dewatering screen, to separate the mixture into a predominantly liquid first region and a predominantly solids second region; withdrawing a stream of liquids and solids from the second region; and introducing a vapour of the same chemical nature as the liquid into the stream at a point downstream of the withdrawal to condense therein and thereby retard liquids flow from the separation zone and concentrate solids in the withdrawal stream. The mass in the second region must be sufficient to permit withdrawal of the solids against the pressure caused by the introduction of the vapour. Suitably, the withdrawal stream is led from the separation zone through a first generally vertical flow passage and then into a communicating generally horizontal flow passage into which the vapour is introduced. The horizontal passage should contain baffles to maintain the pressure of the introduced vapour therein whilst allowing solids flow, e.g. partitions having openings in their lower portions. The resulting solids fraction may be further dried by centrifuging or heating. The introduced vapour has the effect of forming pressure, density and temperature differentials within the separating zone which has a classifying effect with the largest particles becoming concentrated in the solids region and, in the case of a crystallised salt, and the growth of larger crystals of uniform size in the solids region whilst maintaining the suspension of very fine crystals in the liquid. Figure 2 shows a settling tank 20 having inlet 21, feeding into the interior of circular baffle 23, an overflow outlet and a conical lower portion, defining the solids region and leading to the solids outlet. The outlet communicates with a first vertical pipe 30 and a second horizontal pipe 31 into which the vapour is introduced 40. Pipes 32 remove the solids fraction for further drying, e.g. by centrifuging. The method of the invention may be used for the separation of crystallised soluble oxygen, nitrogen, sulphur and/or halide-containing inorganic salts, e.g. ammonium sulphates, phosphotos or nitrates, metallic oxides, crystallised organic material, e.g. naphthalene, or siliceous material from sludge or the flue from stack washing treatments. The Example relates to the separation of ammonium sulphate crystals from a mother liquor solution using steam as the introduced vapour.

Abstract: 1,099,870. Washing machines. H. HERBERTZ. Sept. 29, 1966, No. 43674/66. Heading D1A. [Also in Division F2] A washing and spin drying machine comprises a motor 2 rotatable at high and low speeds to drive the drum at a high speed for spin drying and at a low speed for washing through reduction gear 5 which is displaceable on a shaft 1 driven by motor 2, its housing 6 being coupled with a stationary annular surface 9 by a friction brake when the motor rotates at low speed and axially displaced by a centrifugal device 4 when the motor rotates at high speed so that a drum driving pulley 10 is coupled to the draft 3. The motor shaft 1 is integral with the shaft 3 of the washing machine drum. The centrifugal arrangement 4 comprises half shell 11 fast on shaft 3 and a half shell 12 rotable with, but axially slidable on, shaft) 3 and balls (13 between the shells which, when the motor speed; increases, move outwards and move half shell 12 on shaft 3. During slow running, sun wheel 20 of gear 5 drives planet wheels 22 which roll on a toothed ring 21: in housing 6. Wheels 22 are rotatably mounted on pins 23 mounted in a flange 24 on pulley 10. Housing 6 and pulley 10, are mounted on ball-bearings 26 on the hub 27 of sun wheel 20. A compression spring 30 engages a disc 14 mounted on' the end of shaft 3 and pulley 10 to bias the arrangement to slow running position. When the motor speed is increased; the balls 13 force half shell 12 along the shaft 3, separating-lining 7 from surface 9- and forcing a friction, ring 15 on pulley 10 with engagement withdisc 14 so that wheel 10 is driven directly by shaft 3. The motor is 2-4 pole changing. At its other end 40, shaft 1 carries a pump wheel 41 of a washing solution pump 42 which, when driven at the higher speed, has sufficient delivery height to pump out the solution. In a modification, two spin drying speeds are provided by means of two free wheel devices 54, 55 which connect the shaft to large or small pulleys 10 or 56 according to the direction of rotation motor 2. The drive to pump wheel 41 is direct from the motor and is therefore unaffected.

Abstract: 929,832. Electric selective signalling. NATIONAL RESEARCH DEVELOPMENT CORPORATION. March 14, 1961 [Dec. 30, 1959], No. 44214/59. Class 40 (1). A graphical display of data from a computor in the form of corresponding X and Y digital values is obtained on a cathode-ray memory tube 8 (Fig. 1) under control of instructions fed from the computor to registers 3-5. When X and Y registers 1 and 2 are filled with a number pair for display register 3 receives a signal which after a delay (18) unblanks the tube, enabling the X and Y values, converted to analogue electric signals at 19, 22, to write a point on the screen. This point is retained until erasure is ordered by the computor via register 5. Axes are written on the screen by the computer filling the registers 1, 2 with X, Y values appropriately, and then applying via 4 a signal to circuit 25. This first gates the Y value from 2 to 24, at the same time providing a " linear sweep " signal from circuit 29 which is gated via 20 to the X plates; subsequently a second sweep is applied to the Y plates while the X plates receive the signal derived from 1. Fig. 2 shows the converters 19, 22; except when a sweep signal is applied diode 60 is conducting and 62 not (this is effected by negative and positive voltage signals at 64, 65). The current flowing through 60 to act as input to amplifier 68 (corresponding to 21 or 24 of Fig. 1) is the analogue of the binary digital input at 31-37, since binary 1's are presented as negative signals which cut off corresponding diodes 38-44 and supply currents proportional to their weights to 60. When the inputs at 64, 65 are reversed these currents are diverted through 61, and 68 receives a linearly varying signal via 62.

Abstract: 1,000,458. Photo-electric detection of flaws in transparent sheets. COMPAGNIE DE SAINTGOBAIN. Dec. 13, 1961 [Dec. 13,1960], No. 44668/61. Heading G1A. In a process for the continuous estimation of the polish quality or the body quality of a transparent sheet, wherein a beam of light is directed on to and through the sheet and is reflected back on itself through the sheet by reflecting means on the far side of the sheet, means are provided in the path of the reflected light on the near side of the sheet, to determine a characteristic of the light responsive to the presence of flaws on the transparent sheet. In the embodiment shown in Fig. 1, the image of the slit light source 1 is focused on a small rectangular mirror 4, the same size as the image, inclined to direct the light beam on to a mirror 6 revolving about an axis 10 at the centre of curvature of cylindrical mirror 8, to scan a sheet of glass 7. The light beam is focused on the mirror 10 by lens 5 and is reflected back along its path to pass back through the sheet to be refocused in the absence of flaws on the mirror 4. Scattered light however, caused by flaws in the glass sheet, is not focused by lens 5 on the mirror 4 but passes the mirror and energizes the photosensitive device 9. The optical system 1, 2, 4, 5, 6 and 9 may be turned perpendicular to the paper and oscillate about the axis 10 now coinciding with the optical axis from mirror 4 to mirror 6. In the second embodiment shown, Fig. 2, the mirrors 11 and 12, or the entire system, rotate horizontally about an axis 15 above a plane mirror 15, to scan the glass-sheet in a series of circular scans. Alternatively the mirror 4 may be replaced by a phase plate or a system of doubly-refracting prisms. For the average determination of the quality of a travelling sheet the scanning may be omitted and a light of constant direction used.
